Hello,
I think your topic miss some relevant informations, such as:
- What is your GPU and driver in use ?
- Did you tried these screens, on pure HDMI/DP without USB-C ? Naive question from my side but I'm not aware of this kind of setup.
- All screens manufacturiers and their respective models ?
- Are you using Wayland or X.org ?
- What is your DE and WM as well ?
- How do you log into your DE/WM ? SDDM ? LightDM ? Are you using a xinitrc with startx and what command do you use in that case ?
- What is your profile ?
- What is your kernel in use ?
- Is your Gentoo up-to-date ?
- While booting in this setup, is dmesg giving something interesting ?
- Did you checked logs for X.org or Wayland ?
I might miss some ideas too.
Regards,

- My GPU driver is "intel nvidia fbdev"
- My HDMI screen is detected when connected to the laptop, but not from the dock
- 1. screen (HDMI): Lenovo G70
2. screen (DP): LG 27BK55YP-B
- I'm using X
- I use xinitrc and startx with DWM.
,xinitrc :
| Code: | #!/bin/sh
feh --bg-fill /home/meelo/Images/348205.jpg
. ~/.scripts/xsetloop.sh &
exec dbus-launch --sh-syntax --exit-with-session dwm
|
- profile : default/linux/amd64/23.0/desktop (stable)
- Kernel : linux-6.6.21-gentoo
- Gentoo is up-to-date i think (i did a emerge --sync recently)
- dmesg : https://bpa.st/PEEQ

It lacks what GPUs you have.
We see:
| Code: | | "intel nvidia fbdev" |
As used drivers.
Maybe, I can be naive, you are not using proper driver ?
If you have multiple GPUs, are you having like Bumblebee or something to switch from a driver to another ?
Maybe it uses the wrong card, not able to use 3 screens ?
Do you have another Linux or OS to try that out ?

You might be right about using the wrong driver. I don't know how to see which GPU i'm using, and don't have another OS to try it.
But from past experience i know that the HDMI laptop input work, but i don't have any info from the dock |

Could you please give us the exact list of GPU (manufacturer and model) you are using in your computer, please ?
If you don't know, type:

I have this one the eDP-1 i think :
| Code: | | 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04) |
And this one i think :
| Code: | | 01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1) |

So it's a two GPU computer (laptop, since it's a 1050Mobile, correct ?).
I'm not even sure the 1050 could do that, actually, start to be a bit old isn't it ?
Also, maybe this page would help you: https://wiki.gentoo.org/wiki/NVIDIA/Bumblebee

| It looks like primusrun does not feature spelling correction for the requested program. You will need to spell glxgears correctly if you want to run it under primusrun. |
